'Party time!' Game Of Thrones star Peter Dinklage shows his fun side as he spins in a glow-in-the-dark hula hoop

His portrayal of Tyrion Lannister in HBO's Game of Thrones has won Peter Dinklage an Emmy.

But when he's not outwitting assassins on camera, it seems the 44-year-old actor is busy having fun.

The star shared an Instagram picture of himself on Friday in which he's spinning within a glow-in-the dark hula hoop.

Fittingly, he captioned the photo 'Party time.'

His army of fans were sure to enjoy his silly snap, following another quirky throwback from last week.

Peter posted a high school yearbook photo from 1985, showcasing his cool ways.

The star can be seen posing with an air of insouciant defiance - familiar to those who visit Westeros on Sunday nights - and an epic, voluminous mullet.

Always cool: This picture from Peter Dinklage's 1985 has emerged, proving he's always had it going on

He's bearing the quintessential '80s mop (just a bit more length and it would slot onto one of the heads in Whitesnake) with a similar amount of dignity to that which he displayed as Tyrion faced a farce trial over the murder of his evil nephew, Joffrey, two weeks ago.

But according to the actor, this air of apparent gravitas belied a 'bitter and angry' soul.

Dinklage, who stands at 4ft5, was born with achondroplasia, a common form of dwarfism, and it was understandably hard for him to deal with this as teenager.

Trial by combat: Tyrion learned his fate in episode eight

In an 2003 interview, Dinklage said: 'When I was younger, I definitely let it get to me. As an adolescent, I was bitter and angry, and I definitely put up these walls.

'But the older you get, you realize you just have to have a sense of humour.

'You just know that it's not your problem. It's theirs.'

Of course, his height would make him perfect for the landmark role of 'The Imp' from George R.R Martin's A Song of Fire and Ice series, writ large by HBO.

Dinklage, who also starred in Elf and Entourage, admits he hasn't read the books himself so possibly has no idea of Tyrion's ultimate fate.

It's looking perilous at the moment, however, after Prince Oberyn was crushed in defeat by Gregor 'The Mountain that rides' Clegane during the trial by combat to decide Tyrion's fate.

But with Clegane left looking seriously wounded at the end of episode eight, fans are hoping there's some way the mercurial Lannister can escape his death sentence.
